Immigration policy change in the US

The US has now decided to not deport immigrants who are not a threat to the US. In fact we can go one step further and say US is not deporting immigrants who are beneficial to the US. Every one could clearly see that immigration was great for the US. Even illegal immigration. US had all the labor it ever wanted for her farms and the industry. Labor is shrinking every where and many parts of India is facing an acute shortage of labor. Its a timely move and I hope it is not already late.
